Wehypothese in woorden geformuleerd als datgene wat kunnen hier dezelfde opmerkingen formuleren dan bij de twee andere treatments. Namelijk dat de berekeningen met de software en de getrokken conclusie correct zijn voor de eerste hypothese.
Maar men kan deze berekeningen en deze software niet gebruiken om de andere twee hypotheses te testen en hierover een besluit te formuleren.

Bovendien is het zo dat men - wanneer men een test doet - men uitgaat van het fiet dat de nulhypothese correct is. Wanneer men dus in woorden wil formuleren wat men gaat testen, dient men de nulhypothese te verwoorden. De student heeft echter steeds de alternatieve hij of zij ging onderzoeken.
